' Application Medley 16, 1925. Serial No. 80,481.-

To all whom it may concern: Be it known that I, MATHIAS G. KOEHR- MAN, acitizen of the United States, and a resident of Toledo, in the county ofLucas and State of Ohio, have invented a new and useful Book Stamp,which invention is fully set. forth in the following specifica tion.

This invention relates to advertising devices and is particularlyconcerned with the so-called direct-by-mail system in which customersare solicited individually.

In direct-by-mail advertising it is customary to send in a singleenvelope a form letter together with a pamphlet or booklet illustratinga certain commodity or article together with laudatory or descriptivematter. It frequently happens, however, that the pamphlet or booklet isoverlooked and 39 is never removed from the envelope so that the forceand effect of the advertising campaign is materially lessened.

To overcome this objection, several devices have been attempted but nonehave proved especially successful because each has its own drawbacks.Among these devices is the use of clips, staples or other fasteners forconnecting the pamphlet to the letter, but these are not desirablebecause they tend to tear both the letter and the envelope, andfurthermore are crude and detract from the appearance of enclosures.Another device consists in the provision of an integral extension on aletter sheet and on which advertising matter is placed. "While thislatter device is most ingenious. it affords certain outstandingdisadvantages which prevent its use generally. For example, such a sheetcan only be used to advertise a certain line of commodity and when a newline is brought out, new letter sheets must be made up. In other words,such device is not expansible, and furthermore the writing space on thesheet is considerably reduced.

Objects of this invention are to overcome the objections inherent in theabove devices in a simple manner; and to rovide an advertising devicehaving the unique features of ap lication, construction, and adaptationhereinafter described.

An embodiment of the invention is illustrated on the accompanyingdrawing in which Figure 1 is a perspective view of a letter sheet withan opened book stamp attached thereto; and Figure 2 is a fragmentaryview of the book stamp in closed position.

The illustrated embodiment of the invention comprises a book stamp 1 ofaper or other suitable material consisting 0 any desired number ofleaves, and 1n this instance four leaves are employed, fastened togetherby a staple 3. The book stamp 1 is preferably square or rectangular incon- .5 formation and of relatively small dimen-' sions so as to occupybut a minimum amount of space. The rear page 2 of the book stamp may begummed so that it may be adhesively attached to a letter sheet 4.

The book stamp 1 is used for containing any suitable indicia orinscription, and thus byway of illustration and not of limitation thebook stamp may be used as an advertising medium for the John Doe HatCompany. The various leaves may contain pictures of new models of hatstogether with suitable indicia and identifying inscription, and theseveral pages may be attractivelycolored so that the stamp willimmediately be noticed by the recipient.

It will be apparent that the stamp 1 may be readily and convenientlyattached to the letter sheet 4 by the sender. An outstandingcharacteristic of the invention resides in the fact that the book stampmay be attached to the sheet without in any way interfering with theprinted matter on the sheet, owing particularly to the size and shape.Thus the letter may be written on the sheet 4 and thereafter the stampmay be attached in any convenient place where there is sufficient spaceand where it will be noticeable at once upon opening the letter.

Among the advantages of this device is the fact that the stamp me beattached to the letter sheet without liability of accidentaldisplacement so that the addressor may be assured that the advertisingmatter enclosed will be seen by the addressee. Owing to the fact thatthe stamp does not have to be attached to the sheet until after theletter is written, it will beevident that it in no way interferes withthe typing of the sheet. Furthermore a considerable number of suchstamps can be made up at a com aratively small cost and can be variedaccor ing to the changes inthe commodity or article to be advertisedwithout the in- 110 currence of any materially great cost. Theinnovation and uniqueness of such a stamp will lend itself admirably tothe attraction of the recipients of letters, as will readily be'apreciated.

Wlille this invention has been described and shown as employed in onespecific connection, it is to be understood that numerous changes inapplication, design, size, choice of materials, may effected withoutdeparting from the spirit of the invention, especially as defined in theappended claims.

\Vhat I claim is: 1. A book stam of relatively small roportionsconsistlng of a plurality of caves attached together, and means'on oneof said leaves for adhesively attaching said books to a letter, saidleaves having suitable inscription and indicia thereon for advertisingany desired commodity.

2. A book stamp of relatively small proportions having a pluralit ofleaves, advertis' inscri tions on sai leaves, means for hol ing saileaves together, and means on the rear leaf for adhesively attaching :5

the said stamp to a letter sheet, said stamp being of a size suitablefor attachment to the ordinary letter sheet without obscuring any matterthereon.

In testimony whereof, I have hereunto 30 signed my name to thisspecification.
